new carb??

What intake? 2 or 4 barrel?
Holley Truck Avenger 470 cfm
Edelbrock Performer 500 cfm
Holley 600 cfm Street-Legal Carb
or
Holley 500 cfm 2 barrel
Anything larger than 600 cfm will be too big for a SBF, unless stroked and headers.
Been there - done that on a SBF.
Holley is actually very easy to tune, you just need to follow the supplied instructions.

A 2 barrel runs both barrels all the time, it's not like a 4 barrel where 2 run all the time and the other 2 open when floored.
To replace a 2 barrel with a 4 barrel, you need to change the intake manifold or get an adapter of some sort.
I don't understand why you would have to change the distributor.

I thought you already had a carb on hand? If you are looking for performance, you will not see any improvement installing a 4 brl carb on 2 brl intake.
The 4 brl carbs I mentioned are vac secondary, and will operate with a vac advance factory dizzy.
Let's start over now. You want to improve performance with headers and a 4 brl carb, correct? Leave the dizzy alone for now. Install the headers and carb at the same time. But first, look for a used 4 brl intake to go with the 4 brl carb. Why rejet a carb twice, when you can tune it one time, with a 4 brl intake.
